📦 version 7.3.1, in nixpkgs unstable

💖 i40e_set_promiscuous — set promiscuous mode 💖

okay so bestie, welcome to the i40e_set_promiscuous(9) page from the Kernel API Manual ✨ this is a tiny one — it's basically a one-job function — but it lives in a huge friend group, and you're gonna meet all of them at the end, so buckle up 🎀

🌸 NAME 🌸

i40e_set_promiscuous — set promiscuous mode. that's it. that's the job. no cap 💅

✨ SYNOPSIS ✨

int i40e_set_promiscuous (struct i40e_pf *pf , bool promisc );

it returns an int (the page tells us 0 on success — hold that thought), takes a struct i40e_pf * and a bool. simple. iconic. very demure 🦋

🫶 ARGUMENTS 🫶

  • pf — the board private structure. yes, the board private structure — that's your whole PF's personal little world, and you're handing it over 🔥
  • promisc — promisc on or off. that's the entire vibe check: true = on, false = off 🌈

👑 DESCRIPTION 👑

okay so here's the tea ☕ setting promiscuous mode on a PF is not one-size-fits-all — there are different ways of doing it depending on what state/environment we're in bestie, and it's giving "different doors, same destination" 🚪✨

so what this function does is: it identifies which situation we're in and sets it appropriately. that's the whole assignment. it figures out the vibe and then matches it 💅

Returns 0 on success. that's the only return value this page promises you, so don't come for me about the rest 🙈
